Digital Images can fall into two categories, bitmap or vector, each with their own advantages and disadvantages. For this animation I chose to go with Bitmap assets, as I was inexperienced with using Vectors in the context of animation. However, Vector art does have it's advantages, specifically in regards to motion graphics and rigged animation.
One of the main advantages of using Vector assets in Animation is that Vector files are mathematical definitions, made up of set points with lines and bounds interconnecting them, defined in terms of width, height, ratio and proportion and not dependent on the resolution space assigned to them like Bitmaps are. This means that they can be scaled without effecting the quality and edited with ease, as components can be individually manipulated without effecting the rest of the image. File sizes are also generally smaller as the size is dictated by the intricacy and detail of the points on the graphic.
Vector based art lends itself to certain styles more than others, and this is no different in animation. Vectors are most prominent in motion graphic animations and more commercially oriented work where efficiency of workflow and market viability is prioritised over artistic merit and expression. Often you will find assets created to be vectors are designed around the tools in Illustrator. Illustrator's toolset prioritises simple shapes, curves and lines, and is less suited to more complex drawing.
